Studies of cold climate aerated lagoons conducted by the Arctic Environmental Research Station, Fairbanks, Alaska are reported. Conclusions are based on these studies, observations of full scale aerated lagoons operating in Alaska and reports on lagoons in the northern tier of the United States and Canada. Biological processes which occur in facultative aerated lagoons are reviewed and the performance of cold climate aerated lagoons is examined. Winter and summer performance is compared, and general criteria for the design of cold climate lagoons is presented. Sample calculations for predicting the performance of aerated lagoons are also shown. These calculations are based on the complete mix equation for aerated lagoon design and on the results of the data analysis presented in this report.
